If you visited the official Playstation website today, you may have noticed an interesting teaser. Sony claim they've got an "electrifying announcement" coming on Monday, April 27th.

Intercut with the text of this teaser are pictures of PS3 exclusives inFamous and Uncharted 2: Among Thieves. The first guess would be that it's release date announcements for each but Sony has already revealed the date for inFamous. Also, it's probably too early to nail down a specific day for Uncharted 2.

Lazy guess: both games are going to come to the PSP. If pressed, I could probably come up with a few other half-assed ideas(inFamous and Uncharted 2 action figures?) but April 27th will be here before we know it.
